when we say a thread only needs like 3-4 comments, we don't mean from each player, from each player would be great, but the 3-4 comments is intended to be "total comments" from both players because we know that sometimes threads are slow or real life things happen so we wanted to have an AC but tried to keep it very low to keep it manageable.
Ilsa's thread qualifies, and the thing you linked for Kat doesn't count because it's network - what was used for Dante was a more involved phone/video call later after the texting - but this thread over here has comments in march and can be used since we have said that a thread that straddles two months can only be used for one month's AC and this thread straddles the Feb/March months due to most of the comments being in March, so Kat would make AC as well: https://asylums.insanejournal.com/divisions/10845.html#cutid1
